    Which part of the car must be kept in good condition by law?

    DVSA-style practice question · Safety and your Vehicle

    The answer options

    • Transmission
    • Gearbox
    • Seat beltsCorrect
    • Door locks

    Why that is the answer

    By law, seat belts fitted to your vehicle must be kept in good condition and function correctly. Frayed, cut, or stretched seat belts may fail during a collision, placing occupants at serious risk. While mechanical parts like the gearbox and transmission are vital for driving, safety equipment such as seat belts is specifically regulated by law to protect lives, and their condition is checked during the MOT test.

    How this comes up in the real test

    Questions from safety and your vehicle appear throughout the 50-question multiple-choice section, and the wording changes between versions. Learn the rule rather than the sentence: the DVSA can ask the same point from the opposite direction, and a memorised answer falls over the moment the phrasing moves.

    The pass mark is 43 out of 50, so seven wrong answers is your entire margin. If a whole category is shaky, run the topic practice below until you are getting every question right for the right reason, then go back to full mocks under the clock.
